METAL LACING FOR LAM SHADES.

Application filed April 17, 1928.

This invention relates to lamp shades and metal lacings therefor, and has for its primary object and purpose to provide improved means for securely fastening the abutting vertical edges of translucent shade panels to each other and for securing the end edges of the panels to the top and bottom wire frames of the shade.

It is a more particular object of my invention to provide a metallic lacing strip for such lamp shade panels which can be inexpensively stamped or pressed out in sheet metal embossing dies and variously colored to simulate the ordinary leather lacing.

I propose to produce my novel form of metal lacing with the parts thereof simulating leather loops extending between the apertured edges of the shade panels at right angles to the edges of the panels or in a diagonal direction, or with the simulated loops in crossin g or intersecting relation.

It is a further general object of the invention to provide a. lamp shade and metal lacing or fastening means for the shade panels which may be very inexpensively produced and which will result in the production of a very ornamental and attractive article.

lVith the above and other objects in view the invention consists in the improved. lamp shade and the metallic lacing strip therefor as will be hereinafter more fully describerh illustrated in the accompanying drawing, and subsequently incorporated in the subjoined claims. 7

In the drawing, wherein I have disclosed several alternative forms of my invention, and in which similar reference characters des ignate corresponding parts throughout the several views,

Figure 1 is a side elevation of a lamp shade showing one form of my improved lacing or fastening strip;

Fig. 2. is a fragmentary vertical sectional view on an enlarged scale taken on the line 22 of Fig. 1; i

Fig. 3 is a detail horizontal sectional view taken on the line 33 of Fig. 1, and

Figs. 4, 5 and 6 are fragmentary elevations showing different alternative forms of the metallic lacing strip.

Referring in detail to the drawing, and more particularly to Fi 1 thereof, the side. of the lamp shade may consist of a plurality of panels indicated at 5 in any preferred geometrical arrangement in plan, the said panels Serial No. 270,723.

being cut to proper size and shape from a suitable translucent material, such as mica. celluloid or parchment. Each of these panels in parallel relation to each edge lhereoflis provided with a row of spaced rectangular apertures indicated at 6.

The usual upper and lower wire frames are provided upon which the translucent panels are secured one of these frames being see at 7 in Fig. 2 of the drawings. The several panels are adapted to be arranged with "heir upper and lower ends bearing:- against the outor sides of the spaced frames and with the opposed ver ical edges of adjace 7" panels in abutting contact with each other. These abutting edges of the panels are then secured in fixed relation to each other an d the other panel edges secured to the two frames 7 by means of the metal lacing strips which I shall now describe in detail.

its seen in Figs. 1 and i of the drawings. the lacing strips. which may be readily cut into the required lengths by means of shears. are produced from thin sheet metal, in suitable embossing dies. This lacing strip generally indicated at 8 in the form shown in l consists of the close y adjacent integrally connected concave-convex sections 9, the walls of which are embossed in simulation of a leather lacing extending between spaced e -relets or openings. At this opposite ends of each of these embossed sections 9 the laterally projecting bendable tongues 10 are formed. The sections 9 are of substantially elliptical shape and the longer axes of these sections and of the ton ues 10 are positioned at right angles to the length of the lacing strip in the form shown in Fig. 4 of the drawing.

In the use of this lacing strip, before the panels are assembled on the frames 7 as above referred to, the metal lacing strips are attached thereto, to secure the end edges of the panels to the frames 7, by inserting one ries of the tongues 10 through the ap rtures 6 of the panels and bending the same againstthe inner side thereof. The other series of tongues 10 and the contiguous ends of the sections 9 are then bent inwardly and tightly clinched around the wire fame. The end edges of the panels may thereby be easily. quickly and securely fastened to the wire frames.

The abutting vertical edges of adjacent panels are then connected by additional lacing strips. The tongues 10 are first bent at right angles to the position shown in Fig. 4- and inserted through the apertures 6 in the adjacent edges of the panels, said tongues being then bent inwardly and clinched against the inner faces of the panels 5 as clearly seen in Fig. 3 of. the drawing. In this clinching operation, the alnitting edges of the panels will be drawn tightly together and the sections 9 of the n'ietal lacing strip will extend in an are over the outer surfaces of the edges of the panels, aridging and concealing said contacting edges.

In Fig. 5 of the drawings, 1 have shown the elliptical sections 9 of the lacing strip extending obliquely or diagonally with respect to the length of the strip while in Fig. 6 of the drawing, 1' show another alternative form of the lacing strip in which the elliptical sections 9 are of somewhat less width than in the other forms and are arranged in integrally connected pairs and in intersecting relation to each other in the manner of the ordinary shoe lace.

In this latter form of the device, the bendable tongues 10 project laterally from opposite edges of the strip at an angle with re spect to the longer axes of the sections 9. Any one of these several forms of the metal lacing, when applied to t e lamp shade panels, will produce a very pleasing and attrarw tive effect.

It will be under .ood tint the outer surfaces of the metal lacin strips may be variously colored to either contrast or harmonize with the color of the panels 5, and to represent the various natural or artificially produced color shades of leather.

From the foregoing description, considered in connection with the accompanying drawing, the construction, manner of use and several advantages of my present in'iproveinents will be clearly and fully understood. It will be seen that the metal lacing strip itself may be die stamped from sheet metal at nominal cost, and that the provision of the apertures 6 in the edges of the shade panels to receive the fastening tongues of the lacing strips will result in only a negligible incr ase in the manufacturing cost of such shade panels. Thus, my novel lamp shade and lacing strip may be manufactured and sold without material increase to the purchaser over the cost of such articles now on the market. At the same time, by the use of this metal lacing strip, sinuilating the ordinary leather lacing, greater security in the connection between the panels and in their connection with. the supporting frames is obtained resulting in increased durability in the structure as a whole and a highly attractive ornamental appearance.

I have herein disclosed several desirable and practical embodiments of my present in vention. It will however, be understood that the essential features thereof might also be incorporated in other mechanical forms, and l accordingly reserve the privilege of resorting to all such legitimate changes therein as may be fairly embodied within the spirt and scope of the invention as claimed.
